who named it pythagorean theorem??๐๐

The man on the right is called pythagores, he was the one who discoverd pythagorean theorem so it was named like him.However, he is a greek philosopher and mathematician .His rule is: In a right triangle the square of the length of the hypotenuse is equal to the sum of the squares of the length of other 2 sides. The converse of what he discovered is: if the length of the square of the hypotenuse is equal to the square of the sum of the other 2 sides then this triangle is right.

history!!!!!

More than 4000 years ago,the babyloneans and the chinese already knew that a triangle with the sides 3,4,and 5 must be a right triangle.They used this knowledge to construct right angles. Then a greek scholar named pythagoras was also fascinated by right triangles with these special side rations.He studied them a bit closer and found that the 2 shorter sides of the triangle squared then added together , equal exactly the square of the longest side. And he proved that this doesnt only work for triangles,bur for only right triangles. So, c ^2=a^+b^2

Notes:๐๐

In a semi equilateral triangle:

1- the angle facing 60 degrees=hypotenusw รradical 3รท2

2- the angle facing 30

degrees=hypotenuseรท2
